[0035] In this embodiment, if Figure 1-4As shown, an automatic water supply and cleaning device is disclosed, which includes: a teeth cleaning device 1 and a water replenishing device 2, the teeth cleaning device 1 includes a first shell 1, an oral nozzle 11 installed on the top of the first shell 1, and a first water storage tank 13 and a first pump body 14 placed in the first shell 1, and a water replenishing interface 15 for external liquid to enter the first water storage tank 13 is provided at the bottom of the first shell 1, the water inlet end 141 of the first pump body is penetrated in the first water storage tank 13, and the water outlet end 142 of the first pump body is connected with the bottom of the oral nozzle 11, the first pump body can extract the liquid in the first water storage tank through the water inlet end of the first pump body and output it through the water outlet end of the first pump body, and the output liquid can act on the cleaned area through the oral nozzle, and the user can adjust the spraying direction of the liquid in the oral nozzle in real time by holding the teeth cleaning device, so as to facilitate comprehensive cleaning of the user's oral cavity. The water replenishing device 2 includes a second shell 21, and a second water storage tank 22 and a water supply structure 23 placed in the second shell 21. The water inlet end 231 of the water supply structure is connected to the second water storage tank 22. A water inlet part 24 is provided on the top of the second shell 21. A water inlet channel 241 connected to the water outlet end 232 of the water supply structure is provided in the water inlet part 24. The water inlet part 24 can be connected to the bottom of the water replenishing interface 15 when the first shell 1 is placed on the top of the second shell 21. The user can stably place the teeth cleaning device on the top of the water replenishing device when not in use, which can avoid the teeth cleaning device from tipping over due to being directly placed on the countertop. When the teeth cleaning device is placed on the top of the water replenishing device, the water supply structure 23 can extract liquid in the second water storage tank 22 through the water inlet end of the water supply structure. The extracted liquid can be output through the water outlet end of the water supply structure and replenished into the first water storage tank 13 through the water inlet part 24. The water replenishing device can perform water replenishment operation on the teeth cleaning device when the user is not in use, thereby realizing the automatic water supply function of the teeth cleaning device.

[0036] In this embodiment, if Figure 3As shown in Fig. 4, the upper part of the second shell 21 is provided with a recessed part that is recessed inward, and the bottom of the first shell 1 is placed on the top of the second shell 21 through the recessed part. The recessed part is a placement base 212, and the side wall of the placement base 212 can be wrapped around the bottom of the first shell, which can enhance the stability of the connection between the first shell and the top of the second shell. The placement base is set as a recessed part, which is conducive to the gathering and temporary accommodation of external liquid, and is suitable for large or small random liquid inflows from the outside, which is convenient for users to replenish the liquid in the second water storage tank. The side wall of the placement base is provided with a plurality of water replenishment channels 2121 that are connected to the second water storage tank 22, and the liquid collected in the placement base can enter the second water storage tank through the water replenishment channels. The water inlet member 24 is installed on the top of the water supply structure 23, and is inserted into the placement base 212 through the connection between the water supply structure 23 and the second shell 21. The bottom of the water replenishment interface 15 is provided with a first channel 151 connected to the outside. When the bottom of the first shell 1 is placed in the placement base 212, the water inlet member 24 can be movably connected to the first channel 151, and the liquid output by the water supply structure 23 can be replenished into the first water storage tank 13 through the water inlet member 24. The water inlet member 24 can limit the first shell from tipping over or moving to the side by being connected to the water replenishment interface 15 along the axial direction, which is beneficial to enhancing the stability of the first shell when it is placed on the top of the second shell.

[0037] In this embodiment, if Figure 5-7 As shown, an overflow channel 131 is provided at the bottom of the first water storage tank 13 along the axial direction, and the overflow channel 11 is communicated with the outside through a water outlet 132 provided at the bottom of the first water storage tank 13. The overflow channel includes a connector 1311 protruding inward from the bottom of the first water storage tank and an overflow pipe 1312 sleeved on the top of the connector. The channel in the connector can be communicated with the outside of the first shell through the water outlet, the top of the channel in the connector is communicated with the overflow pipe, and an overflow distance is provided between the overflow pipe 1312 and the top wall of the first water storage tank. When the liquid level in the first water storage tank is higher than the top of the overflow pipe, the liquid above the top of the overflow pipe can flow into the overflow pipe and be discharged through the outlet. The maximum capacity of the liquid entering the first water storage tank can be controlled by the overflow channel to prevent the external liquid from continuing to replenish the first water storage tank when the liquid in the first water storage tank reaches the maximum capacity, so that the water in the first water storage tank is excessive and causes a malfunction. The safety of the product operation can be guaranteed by discharging the excess liquid.

[0038] In this embodiment, the second shell 21 includes an upper shell 213, a shell side wall 214 and a lower shell 215. The upper shell 213 is an open shape formed in a ring shape, and the upper shell 213 is a concave shape at the bottom with a cross-sectional diameter gradually decreasing from the top to the bottom in an arc shape. The bottom of the upper shell 213 is connected to the top of the water supply structure 23 to form a placement base 212. The top of the shell side wall 214 is closed and connected around the top of the upper shell 213, and the bottom is connected to the top of the lower shell 215. The bottom of the first shell is provided with an arc-shaped side wall 111 higher than the bottom of the shell, so that the arc-shaped side wall 111 at the bottom of the first shell 1 fits into the placement base 212, which is beneficial to improve the stability of the first shell placed on the top of the second shell. The water outlet 132 is arranged on the curved side wall 111. The water outlet 132 can be placed in the placement base 212 together with the connection between the bottom of the first shell 1 and the top of the second shell 21. The overflowed liquid can enter the second water storage tank 22 through the water replenishment channel 2121, which can prevent the overflowed liquid from being discharged onto the placement platform due to the lack of a collection device, thereby causing pollution to the placement platform. The overflowed liquid can be collected to prevent unused liquid from being wasted due to overflow. The design of the water outlet on the curved side wall can make the outflowing liquid be at a high position on the placement base, which is conducive to the outflowing liquid entering the second water storage tank.

[0039] In this embodiment, if Figure 8 As shown, a switch structure 16 is provided in the water replenishment interface 15, including an upper water channel 161 and an active valve 162 disposed in the upper water channel 161. The upper water channel 161 can be connected to the first water storage tank 13 and the bottom is connected to the first channel 151. The liquid replenished through the water inlet can enter the upper water channel through the first channel and enter the first water storage tank through the upper water channel. The bottom of the movable valve 162 can open or block the top of the first channel 151 through the thrust change generated by the squeezing of the water inlet member 24. When the bottom of the first shell is placed in the placement base, the water inlet member can be connected to the first channel as the first shell is placed, and the top of the water inlet member 24 can squeeze the bottom of the movable valve through the first channel. The movable valve moves into the upper water channel due to the squeezing of the bottom by the water inlet member. At this time, the bottom of the movable valve is separated from the top of the first channel, and the liquid output by the water inlet member can enter the upper water channel as the top of the first channel is opened, and enter the first water storage tank through the upper water channel. When the bottom of the first shell is not placed in the placement base, the bottom of the movable valve cannot be squeezed by the water inlet member into the upper water channel through the entry of the water inlet member. At this time, the bottom of the movable valve is blocked at the bottom of the first channel. The tooth washing device can select external liquid to enter the first water storage tank through the opening state of the top of the first channel by the movable valve, which is beneficial to prevent the liquid in the first water storage tank from flowing out through the first channel, and is convenient for the user to take and use the tooth washing device.

[0040] In this embodiment, if Figure 6 Or as shown in 9, the water supply structure 23 includes a third shell 233 installed in the bottom of the second shell 21 and a second pump body 234 placed in the third shell 233, the bottom of the third shell 233 is surrounded by a recessed ring 2331 along the outer wall, and a side wall edge 2332 extending outward is provided at the top of the outer wall of the recessed ring 2331, the top of the third shell is connected to the top of the upper shell to form a placement base, the outer side of the side wall edge 2332 is connected to the bottom of the shell side wall 214, and the second water storage tank 22 is formed by the closed connection of the shell side wall 214, the upper shell 213 and the third shell 233, the third shell can isolate the second pump body from the second water storage tank, prevent the second pump body from contacting the liquid in the second water storage tank and affecting the second pump body, thereby ensuring the normal operation of the second pump body. The side surface of the bottom of the third shell 233 is provided with a second channel 2333 that can connect the second water storage tank 22 with the water inlet end 2341 of the second pump body. The second channel passes through the recessed ring. The side surface of the bottom of the third shell 233 protrudes into the recessed ring 2331 and is provided with a pumping portion 2338. The pumping portion 2338 forms a pumping cavity 2334 that passes through the third shell 233. A pumping pipe 2335 extending into the third shell is provided on the inner wall of the pumping cavity 2334. The second channel 2333 is placed in the pumping cavity 2334. In the water pipe, the interior of the third shell can be connected to the second water storage tank through the second channel. A first hose is sleeved on the water pumping pipe. The other end of the first hose is connected to the water inlet end of the second pump body. The second pump body can extract the liquid in the second water storage tank through the second channel. The recessed ring is the bottom of the second water storage tank. The water inlet end of the second channel is connected to the recessed ring, which is beneficial for the pump body to extract the liquid at the bottom of the second water storage tank, preventing residual liquid in the second water storage tank and increasing the utilization of the liquid in the second water storage tank.

[0041] In this embodiment, the bottom of the placement base 212 is provided with a base channel 2122 formed by the upper shell 213 in an annular shape, the top of the third shell 233 is provided with a shell protrusion 2336, the shell protrusion 2336 can be placed in the base channel 2122 with the connection between the top of the third shell 233 and the bottom of the placement base 212, the outer wall of the shell protrusion is fitted and connected with the inner wall of the base channel, the water inlet is arranged on the top of the shell protrusion and placed in the placement base with the shell protrusion, the placement base can limit the horizontal movement of the third shell through the connection with the shell protrusion, which is conducive to increasing the stability of the connection through the mutual restriction of the connection between the installation base and the third shell. The water outlet 2342 of the second pump body is connected with the bottom of the water inlet 24 through the top of the shell protrusion, the liquid extracted by the second pump body can be output to the water inlet through the water outlet of the second pump body and output through the water inlet, when the bottom of the second shell is placed in the placement base, the water inlet entering the first channel can put the output liquid into the first water storage tank through the water inlet channel 241.

[0042] In this embodiment, if Fig.10 Or as shown in 11, the water supply channel 161 includes a water supply pipe 163 arranged at the top of the water replenishment interface 15 and a water inlet chamber 164 arranged in the water replenishment interface 15, the water inlet chamber 164 is connected to the outside through the first channel 151 in the bottom water replenishment interface 15, and the water inlet chamber 164 is connected to the outside through the first channel 151 in the bottom water replenishment interface 15, and the water inlet chamber 164 is provided with at least one third channel 165 connected with the first water storage tank 13 through the side wall of the water replenishment interface 15, and the liquid entering the water inlet chamber can enter the first water storage tank through the third channel, and the top of the water supply pipe 163 is sleeved with one end of the second hose, and the other end of the second hose is penetrated outside the first water storage tank and connected with the water inlet end 141 of the first pump body, and the liquid in the first water storage tank and the liquid in the water inlet chamber are connected through the third channel, and the first pump body can extract the liquid in the first water storage tank through the water supply pipe connected with the water inlet chamber. The movable valve 162 is placed in the water inlet chamber 164, including a water retaining member 1621 and a support member 1622 connected to the top of the water retaining member 1621 in an annular shape. The bottom of the water retaining member can cover or open the top of the first channel. The bottom of the water supply pipe 163 extends into the support chamber 1623 formed by the support member 1622. The top of the support member 1622 is connected to the top wall of the water inlet chamber 164. At least one fourth channel 1624 connected to the water inlet chamber 164 is provided on the side wall of the support member 1623, and the support member 1622 is an elastic member. A support edge is extended to the circumferential side of the top of the support member, and the support edge is connected to the top wall of the water inlet chamber. The connection width between the support member and the top wall of the water inlet chamber can be increased through the support edge 1625, thereby enhancing the airtightness of the support chamber and the water inlet chamber, so that the support chamber is connected to the water inlet chamber only through the fourth channel.

[0043] In this embodiment, when the bottom of the first shell is placed in the placement base, the water inlet member can generate a thrust toward the water inlet cavity on the bottom of the water retaining member through the first channel, and the support member can be deformed and compressed by the inward movement and extrusion of the water retaining member. The bottom of the water retaining member can be separated from the top of the first channel by the deformation and compression of the support member, and the top of the water retaining member can be shielded by the bottom of the water supply pipe by the deformation and compression of the support member. At this time, the top of the first channel is in an open state and the bottom of the water supply pipe is in a closed state. The opening of the top of the first channel can allow the liquid output by the water inlet member to enter the water inlet cavity along with the top of the first channel, and enter the first water storage tank through the third channel. The closing of the bottom of the water supply pipe can prevent the liquid entering the support cavity through the fourth channel from being placed in the water supply pipe, which is beneficial to the bottom due to the impact of the water flow output by the water inlet member to cause the liquid to flow back to the outside of the oral nozzle through the water supply pipe, thereby preventing the placement table from being contaminated by liquid seepage when the user is not in use. When the first shell is separated from the top of the second shell, the top of the water inlet member cannot act on the bottom of the water retaining member, and the water retaining member no longer generates an inward squeezing force on the supporting member. At this time, the supporting member can generate an outward thrust on the water retaining member due to the recovery and extension of the elastic member. The water retaining member can use the outward thrust of the supporting member to block the bottom of the first channel from the top, so that the top of the first channel is in a closed state, and the top of the water retaining member is separated from the bottom of the water supply pipe due to the recovery and extension of the supporting member, so that the bottom of the water supply pipe is in an open state, so that the liquid in the first water storage tank cannot leak out through the first channel due to the closure of the top of the first channel, which is convenient for the user to take and use the tooth washing device, and the liquid entering the support cavity through the first channel can enter the water supply pipe as the bottom of the water supply pipe is opened, so that the first pump body can extract the liquid in the first water storage tank through the water supply pipe and spray it out through the oral nozzle, thereby completing the user's oral cleaning work. A downwardly protruding limiting portion 1626 is provided at the bottom of the water retaining member. When the top of the water inlet member and the bottom of the water retaining member are pressed against each other, the limiting portion can be limited to the top of the water inlet channel through the top of the water inlet member, thereby preventing the water inlet member from sliding with the bottom of the water retaining member during the extrusion process, so that the top of the water inlet member can fully apply the extrusion force to the water retaining member.

[0044] In this embodiment, as shown in 10-12, the bottom of the first shell 1 is provided with a mounting channel 112 that is connected to the outside, the water replenishment interface 15 includes a mounting base 152 and a cover body 153 connected to the top of the mounting base 152, the peripheral side of the mounting base 152 is connected to the inner side of the mounting channel 112, the cover body 153 includes a top plate 1531 and a cover side plate 1532 connected around the peripheral side of the bottom of the top plate 1531, the bottom of the cover side plate 1532 is connected to the top of the mounting base 152 and forms a water inlet chamber 164 in the cover body 153, the first channel runs through the upper and lower ends of the mounting base and is connected to the water inlet chamber, the water inlet chamber is provided with a plurality of side plate channels 1533 that are connected to the first water storage tank through the peripheral side of the cover side plate, the bottom of the side plate channel runs through the bottom of the cover side plate and is placed on the mounting base, the third channel 165 is the side plate channel 1533, and the liquid entering the water inlet chamber through the top of the first channel can enter the first water storage tank through the third channel. The bottom of the water retaining member placed in the water inlet chamber can abut against or separate from the top of the mounting base as the support member deforms, and the top of the first channel can be shielded or opened by abutting against or separating from the top of the mounting base. The support member is connected to the top of the water retaining member in an open shape, and forms a support chamber 1623 by connecting to the top wall in the water inlet chamber.
